TIRE-VALVE ATTACHER.

SPECIFICATION forming part of Letters Patent No. 650,424, dated May 29.1900- Application filed June 10, 1896 Serial No. 594,917. (l lo moclehl7 To all whom it may concern.-

Beit known that LGEORGE H.F.SCHRADER, a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Tire-Valve Attachers, of whichthe following isa specification.

This invention relates to tire-valves, and aimsto provide improved meansfor attaching these to the tires of bicycles and the like.

It is found that in using shoe-valves or valves having a flange passingthrough and clamped within a pneumatic tire there is difficultyinmaiutaininga tight joint and danger that the tire will be torn at thejoint or so weakened as to be unable to resist the airfore I haveendeavored to improve the con- .nection of the valve with the tire byinterposing an attaching-strip between the tire and the valve, whichstrip when cemented to the tire reinforces the latter and assists inpreventing leakage. Such a construction is claimed in my applicationfiled November 13, 1895, Serial No. 508,780. My present invention aimsto provide means whereby the valve can be clamped both to the tire andto the attacher, whereby all the strength and leakproof qualities of thelatter are availed of, and the strength of the tire where clamped to thevalve is also utilized, as distinguished from my former construction, inwhich the valve was preferably clamped only to the attacher, and thenboth were applied to the tire bycementing the attacher thereto.

In carrying out my present invention in its preferred form I providecertain features of improvement, which will be hereinafter fully setforth.

In the accompanying drawings, Figure 1 is a fragmentary side elevationof a .tire and valve attached together according to the preferred formof my present invention, the felly of a wheel being shown in section.Fig. 2 is a fragmentary .plan view thereof, the valve being in sectionon the line 2 2 in Fig. 3. Fig. 3 is a fragmentary section of the tireand valve, cut on the axis of the latter, showing the parts in theattached position. Fig. 4 is a fragmentary side elevation of the valve,

showing the attacher and other parts separated and the whole in positionfor applica tion to any tire; and Fig. 5 is a fragmentary sectionanalogous to Fig. 3, but showing a modification.

Referring to the drawings, I will now describe in detail my presentimprovements.

Let A represent a pneumatic tire; B, the felly of a wheel; 0, atire-valve; D, an attacher therefor; E, a clamping-nut screwing on theexternal screw-thread F of the valve; G,a shoe or flange at the innerend of the valve; H, a nut holding the valve on the felly; I, avalve-socket in the telly; J, a shoulder on the clamping-nut fittingthis socket, and K an antifriction metal disk or washer between the nutE and attacher D. As far as described the parts may be of any usual orsuitable construction.

According to one feature of improvement I pass the flange or shoe G ofthe valve through the hole a of the tire so that it shall embrace theinner face of the latter, and I provide the attacher D at the outer faceof the tire, passing it over the valve by inserting the body of thevalve through the hole I) in the attacher, so that the latter can becemented to the outer face of the tire, and then the tire and attachercan be clamped together to the valve by screwing home the nut E on thelatter until these parts are compressed to the desired degree to effecta tight joint and a suitable engagement. If desired, the rubber washer Lor other suitable washer may be employed between the flange G and theinner face of the tire, as the washer K can be interposed between theattaching-flap D and the clamping-face of the nut. The reduced neck 0 ofthe, valve is made long enough to give roomfor these parts about theflange Grand terminates in the shoulder d, which is the lower end of thescrew-thread F, which thread is preferably of slightly-greater diameterthan the hole Z2 through the attacher, so that the shoulder tends toretain the attacher and parts below it in place when these parts areassembled as an attachment ready for appli-.

cation to any tire. In Fig. 4 the attacher is shown for clearness asmoved up over the threads, or in one of thepositions-it'would occupywhile being applied to the valve.

The attacher preferably consists of an oblong, circular, or othersuitably-shaped sheet of rubberand textile material,the sheet shown;

having a bottom rubber face 6 and a top of cloth or other textilematerial f, these parts being firmly united in the formation of thesheetin any suitable manner. When applied to the tire, the rubber faceof the attacher is firmly and tightly cemented to the tire, making aleak-tight joint around the valve, while its cloth back serves, byadhesion to the rubber face, to resist tearing or bursting strains.

The clamping-nut E compresses both the attacher and the wall of the tireto some extent and makes a leak-tight joint around the valve, betweenthe inner face of the tire and the adjacent face of the flange G. Whenused, the rubber washer L assists in securing a leak tight joint andcushions the action of the flange against the tire. \Vhen the nut E isscrewed home, its active face passes somewhat inwardly of the shouldercl. In its position in the socket of the felly its outer shoulder Jextends within and snugly fits the cylindrical Walls of the socket I.This shoulder is cylindrical and of much smaller diameter than thenut-body and is connected thereto by a contracted neck 9, below whichthe nut is a thin wide member having a convex top face and a smoothbottom face fitting the disk K. This disk is a thin sheet=metal ringpassing over the valve C and having a rounded or upwardly-bent edge toavoid injuring the attacher.

If desired, the attacher and tire may be clamped directly togetherbetween the flange and nut of the valve, as shown in Fig. 5; but Iprefer to interpose between the adjacent faces of the tire and attachera thin annular washer M. (Shown in Figs. 3 and 4.) This is preferablyathin flat sheet=metal ring large enough to slip over the shoulder cl andof nearly the same diameter as the nut E. This is a loose ringseparating the surfaces of the tire and attacher where these parts areclamped between the nut and flange. In practice I find it advantageousto employ this ring.

In use the valve, with the attacher, washer or washers, and nut Eloosely assembled, as shown in Fig. 4, will be supplied as an attachmentready for application to any tire, or they may be assembled at the timeof application to the tire. The use of the rings, disks, and washerswill be varied as circumstances dictate.

' It will be seen that my invention provides improvements which can bereadily and advantageouslyavailed of, and it will be understood that theinvention is not limited to the particular details of construction andarrangement set forth as constituting its preferred form.

What I claim is 1. The tire A,and valve C extending through the tire andhaving a flange therein, in combination with a felly B having avalve-socket I, and a clamping-nut E screwing on said valve and having ashoulder J snugly fitting said socket, and a reinforce-attacher Dadhering to said tire and clamped by said nut to said valve, betweensaid nut and the outer face of said tire, whereby creeping of the tireis prevented by said shoulder, and the creeping strains are transmittedto the valve by both the tire and attacher.

2. As a new article of manufacture, a valve having a wide flange G,asmall screw-threaded body for fitting a socket in a wheel-felly, and areduced cylindrical portion 0 between said flange and body, incombination with an attacher D clamped to said valve having an aperturesurrounding said neck, and having an annular face, opposed to and ofgreater size than said flange, adapted to be cemented to a pneumatictire, and a nut E screwing on said body toward said attacher, saidflange adapted to be inserted in a hole in such tire, and said neck of alength equaling the thick ness of the wall of such tire and of such attacher, and said nut adapted to' clamp such wall and attacher betweenitself and said flange, said valve adapted to resist creeping of thetire, and said reinforce adapted to transmitsuch creeping strains tosaid smooth neck.

3. The combination with a wheel-felly having a valve-socket, of a tirehaving a hole opposite said socket, a reinforce-attacher cemented tosaid the around said hole and having a hole coinciding with that in thetire, a valve having a body fitting such socket, an external screwthread, and a flange at its lower end, passing through the holes in boththe tire and attacher, engaging the inner Wall of the tire with saidflange, and preventing creeping of the tire on the felly, and a nutscrewing on the Valve against the outer face of the attacher andclamping the latter and flange, whereby. creeping strains aretransmitted through both the tire and attacher.

4. The combination with a wheel-folly hav ing a valve-socket, ofa tirehaving a hole opposite said socket, a reinforce-attacher cemented tosaid tire around said hole and hav- 1 ing a hole coinciding with that inthe tire, a

valve having a body fitting such socket, an external screw-thread, and aflange at its lower end, passing through the holes in both i the tireand attacher, having a smooth exterior opposite both, engaging the innerwall of the tire with said flange, and preventing creeping of the tireon the felly, and a nut screwing on the valve against the outer face ofthe attacher, and clamping the latter and the tire'to the valve betweenthe nut and said flange, whereby creeping strains are transmittedthrough both the tire and attacher, and are received by the smoothexterior of said valve.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
